XSeen Examples

The importance of examples in learning a new language cannot be overstated. This section contains illustrative examples of using XSeen. As has been discussed there are a number of similarities between XSeen and A-Frame and X3D. These will be obvious in the examples. It is possible to intermix tags from each language in a manner that makes sense.

Integrating X3D into DOM - Case Sensitivity

The X3D language uses mixed case node and field names. In some cases field values are specified as case-specific names. This is standard XML. HTML allows for any case and converts tags and attribute names to lower case before use. The HTML language does not impose specific case requirements on attribute values. XHTML is XML-based, so it is case sensitive; however, all tag and attribute names are defined as lowercase.

Introducing XSeen

HTML gained wide-spread acceptance because it was straight-forward and produced results even if you did write it perfectly - it is very forgiving. Of course, you get better results when written correctly, but you are never puzzling out what IEA102A INVALID PARAMETER/FORMAT - RESPECIFY means1. HTML presents a unified environment to the web designer and user.

XSeen

XSeen is a tool for the purpose of developing the next generation standard for declarative 3D and Virtual Reality content on the Web. It is designed to function completely integrated with the DOM and incorporate the best features of X3D, A-Frame, and other declarative 3D languages. It is written in JavaScript and built upon THREE.js. It is fully open source with the code base dual-licensed as MIT and GPL. The documentation is Creative Commons Share-Alike.

XSeen: Merging X3D and A-Frame

This post introduces XSeen - a declarative language built on A-Frame and X3D to achieve the desire of a fully declarative 3D/VR language that runs in the web browser. In this initial release the language supports some X3D and some A-Frame nodes and capabilities. It is possible to combine the two to produce results that are the available in either.

Purpose of X3D - Display

This is the fifth in a series discussing the next generation of X3D and addresses the needs and requirements for X3D for the display of 3D, AR, and VR content in the current ecosystem of display devices and environments. The 3D content is displaying in a larger ecosystem of including the user’s computer, browser, Internet, and originating server. As such it needs to work cooperatively within the environment and with other content already displaying in that environment.

Purpose of X3D - Archive

This is the fourth in a series discussing the next generation of X3D. Archiving and long-term storage has always been a strong point of X3D. The ability to read and play content from years or even decades ago makes it unsurpassed in the 3D world. X3D has human-readable formats that can be used for archiving so that the content does not require special software to unpack and display the file contents. It is important to keep the long-term storage and access capability while along X3D to stay current with advances in display technology.
